Specification of Letters Patent.

Application filed May 4, 1916. Serial N0.'95,389.

To all whom it may concern:

Be it known that I, JOSIAH BRADLEY, a citizen of the United States, and a resident of Brooklyn borough, New York city, and State of New York, have invented certain new and useful Improvements in Operating Mechanism for Bottle-Capping Machines, of which the following is a specification.

My invention relates to that class of bottle capping and sealing machines in which sealing disks are conveyed insuccession by a rotary conveying device or carriage from a supply box, stand or stack, to the bottle or other container to be capped and sealed; and more particularly to such machines as employ an intermittently rotated turret or drum, which serves as a part of, or base for, the rotary carriage or conveyer.

The objects of my invention are to provide a new -drive for the turret and locking means for the same; a new drive for the bottle-feeding apron, and adjusting means for the same; as well as looking and positioning means for the upright driven shaft, through which the apron is quickly and accurately positioned for quart, pint and half pint bottles.

In the accompanying drawings I have shown only such parts of the main machine as seem necessary for the easy understanding of the novel details above mentioned.

Figure 1, is a side elevation of the entire machine.

Fig. 2, is a fragmentary view showing the turret operating mechanism, looking from the rear.

Fig.3, is a vertical section on line 33 of Fig. 2, on a larger scale.

Fig. 4, is a detail section on line 44 of Fig. 3.

Fig. 5 Fig. 1. o

Fig. 6 shows a fragment of the cone clutch in elevation, having the graduation and pointer for the quarts, pints and half-pints.

Fig. 7 is a detail section on line 7-7 of Fig. 1, on a larger scale.

Fig. 8 is an enlarged elevation of the pin disk transmission from the main shaft, showing the locking means free to move.

Fig. 9 is a section on line 99 of Fig. 8.

Same letters indicate similar parts in the different drawings. I

A, is the standard or supporting frame of is a detail section on line 55 of the machine upon which the moving parts are mounted. B is the plunger head moved up and down by the rod a, which is operated by the counterbalance lever C, pivoted to the frame at I) and driven by the toggle lever D and compound lever E, journaled in the framework respectively at 0, (Z. The lower end of the compound lever E carries a roller (not shown). This lever is operated from the motor F in the usual manner, through the gears, shafts, worm and wormwheel, shown in Fig. 1, the latter being mounted on the main shaft 6. Any other means of imparting rotation to the main shaft 6 may be adopted in place of those shown if desired. My present invention has nothing to do with these parts of the machine, which are only shown for clearness of description of the novel mechanism which I have introduced in this general type of machine.

In addition to reciprocating the plunger head and plunger head casing and operating the other movin parts of the bottle capping and sealing mac ine, power is derived from the main shaft 6 to impart the requisite intermittent motions to the turret and conveyer to which this present application more particularly relates.

To this end I mount upon the main shaft e, a pin-disk or wheel W, which carries a single pin f,.near its outer edge, and is provided with two shallow cut-away portions 9, g, of which the larger is in advance of the pin 7', and the smaller 9 in its rear.

The vertical driven shaft 6', journaled in brackets projecting from the standard A, carries at its lower end a channeled during the greater part, of its revolution,

and during this period the shaft 6' remains stationary. As soon as the cut space gcomes opposite a buffer pin, the latter has nothing to press against and the pin 7, (see Fig. 8) enters the mouth of the channel k, or k Patented Oct. 15, 1918.-

cut portion 9 comes around when this buffer pin slips in and permits the pin f to enter the succeeding channel and impart another half revolution to the shaft 1:.

At the upper end of the shaft 6 is a worm I, which engages a gear J, on shaft e",

journaled in a bracket on the standard A,

and carrying a pin-gear K, which, as shown, is provided with eight pins, j, j.

On the lower end of the turret G, is a pin gear L, the teeth of which are engaged by the pins j, j, at such intervals that the turret is given the desired four stop intermittent revolution required to harmonize its motions with the other parts of the bottle capping machine as usual.

To look the turret. I provide a spring pin 0 inclosed in a casing M, (Fig. 3) which is normally held by the spring is, in one of the four holes, Z, Z, in the periphery of the pin gear L. This spring controlled pin 0) is drawn out,of-the hole in which it happens to be, to allow the turret to make a quarter turn by the rocking of a cam-operated arm N, pivoted at m in a bracket on I the standard A. On the lower end of this arm N, is a cam surface n, over which plays a spring-held pawl 0, on the block which is fastened to the reciprocating case of the plunger head.

When the plunger is down capping a bottle the turret remains locked and the pawl o is below the cam 11.. As the plunger head rises and with it the block p the cam end of the arm M is deflected vby the pawl and thus the spring pin 4; is drawn out of the hole Z and remains out, presslng against the periphery of the turret, while the turret makes a quarter revolution. On the downward stroke of the plunger and block the pawl passes the cam surface without displacing it. It will thus be seen that whenever the plunger head rises the turret is released for a quarter turn and is automatically locked by the spring in U as soon' as that turn is complete, by w ich time the plunger has come down again to cap another bottle.

Instead of driving the bottle-feed apron by a complicated system of gearing as is sometimes done, I provide a very simple and effective direct drive from the shaft c.

At some convenient spot on the vertical shaft 0' I mount a toothed gear 0, (Fig. 5') which meshes with a worm P, on shaft 9. This shaft carries a sprocket Q, which I utilize as the driving sprocket for the feed chain R, the other usual sprockets being idlers.

There remains to be described the means for adjusting the throw of the bottle-feed apron to the various sizes of bottles, that is quarts, pints, and half pints. This I accomplish in a very simple and effective manner by means of a cone-clutch S, S, of which S, represents the male member and S the female member. Instead of mounting the sprocket Q, directly on shaft 9, I mount it on the sleeve 7, on which the female member S is mounted. By turning the male member S, secured to shaft 9 by the hand nut T, so that the pointer s will register with the desired size as indicated on the graduated scale t, on the female member S the throw of the sprocket is regulated accordingly.

I claim An operating mechanism for bottle capping machines which comprises a plunger head casing, a conveyer turret having a number of locking holes arranged around its periphery, a spring controlled bolt adapted to engage each of said holes in turn as said turret revolves, a rocker arm pivoted to the frame of said machine and a cam mounted upon the plunger head casing and operating to rock said arm at intervals to disengage said bolt from said turret, and permit the same to rotate.
